How to Add Mechanical Keyboard Sounds on Mac

Battuta listens for physical key-down and key-up events, then plays matching recordings with low latency. It runs from the menu bar, so the same keyboard profile works while you type in Safari, Chrome, VS Code, Terminal, Notes, or a chat app.

The selected samples are preloaded as 48 kHz PCM audio. A keystroke therefore triggers an in-memory lookup and playback instead of reading or converting a file in the input path.

macOS only lets an app receive system-wide keyboard events after you grant Input Monitoring permission. Battuta needs those events so a key can make a sound even when another app is in front.

That permission is broad at the operating-system level, but Battuta uses only hardware key codes, button identifiers, and down/up state. It does not read characters, passwords, pointer location, or the contents of the active window. Aggregated typing statistics stay on the device, and the source code is public for inspection.

Start with a built-in mechanical profile, then tune the volume and natural variation. Press and release recordings are handled separately, which makes the result feel less like a single sound pasted onto every key.

The DIY editor accepts common audio formats and lets you assign a general sound, keyboard rows, large keys, or an individual key. Completed packs can be exported as a .simuboardpack file and moved to another computer.
